A million thanks to Sony! A lot of improvement especially for UI Design, new notification,new walkman widget, new battery icon, show a percentage, same like samsung notifications. The most awesome the colour of notifications follow by the theme we choose. AHHHHH I fall in love with the new update, I know Sony didnt dissapointment eventhough Xperia J is a mid-range Android phone. Btw, keeps update for the build number, still like lagging when plays music. THANKS SONY!

Hi Mocix! It appears that your problem was similar to me. But in my case was a bit different. My Xperia J somehow could connect itself to the WiFi Network. But then in the meantime, the signal grown weaker and vanished all of a sudden. . .

Have you experienced that thing in the first place? Since that was the next thing I've experienced once updated my device to JB.

Battery drain is caused by 'qosmgr' process that permanently eats CPU recources and makes phone laggy. usualy this process is activated when kernel governor conservative is used. SONY should fix this. Than the phone will be smooth again. Or you can root your phone if you have knowledge how to do it and modify governators yourself.

I have a similar but more serious problem.... no data connection at all after the upgrade.  The phone communication and wifi connection are still normal, but no data via 3G can be obtained.  All things I can think of have been tried, including rebooting, remove SIM card, etc., but still no clue to solve the problem.

I feel very frustrate about this… can anyone suggest me the way to revert the phone to the pervious version?

Do you have APN for interner defined after the upgrade?

settings>more... >mobile networks > access points names.

there should be at least one for internet
